Your car petrol usage is 9 litres / 100 km. Your tank holds 68 litres. How many tanks of fuel will you use to drive 1500km?

To find out how many tanks of fuel you'll need for a 1500 km drive, we first calculate the total fuel consumption and then determine how many full tanks are required.

1. **Calculate Total Fuel Consumption:**

   The car uses 9 litres per 100 km. For 1500 km, the fuel consumption can be calculated as follows:

   \[
   \text{Fuel Consumption} = \left(\frac{9 \text{ litres}}{100 \text{ km}}\right) \times 1500 \text{ km} = 135 \text{ litres}
   \]

2. **Calculate Number of Tanks Needed:**

   The tank capacity is 68 litres. The number of tanks required is:

   \[
   \text{Number of Tanks} = \frac{135 \text{ litres}}{68 \text{ litres/tank}} \approx 1.985 \text{ tanks}
   \]

   Since you cannot use a fraction of a tank in reality, you will need to fill up 2 full tanks of fuel to cover the 1500 km.

**Answer: You will need 2 tanks of fuel to drive 1500 km.**
